Description
Technical field
The present invention relates to a kind of processing technique equipment and the method for marine low speed diesel engine, use light-duty particularly to one
The crankshaft-flywheel of Boring machine, with the full circle swinging automatic position machining device of drill reaming and method, belongs to machinery manufacturing technology field.
Background technology
Bent axle plays vital effect as the core component of marine low speed diesel engine main frame for power output.Ship
Being all heavy parts with the component of low-speed diesel engine, its volume is the hugest, and the cylinder diameter of main frame is from 600mm to 980mm, weight
Amount has reached 200～300t especially.
Connection member on bent axle is different according to different main frame configurations, usual bent axle need to according to type require with
Flywheel, sprocket wheel (non-cylinder sleeve type) are connected with front end balance weight.In rotation process, flywheel and balance weight can utilize the weight of self
Amount overcomes the vibration that main frame produces, and meanwhile, makes bent axle also be able to when Main Engine Cut-Off continue by flywheel with engaging of turning engine
Rotating, sprocket wheel is then the pivotal role playing the output energy that the kinetic energy produced by piston by Chain conveyer is changed to bent axle.On

The major way of at present connecting hole processing can be divided into two kinds: 1, crankshaft drilling template way, and 2, bent axle prebored hole mode.
Both difference are, the former can be mounted directly after processing, and reprocess when the latter needs the later stage to assemble.
In bushing plate processing mode, although need not reprocess before bent axle assembling, but when sometimes there is also assembling, connecting hole goes out
The problem of existing little deviation, and the processing cost of which is the highest.
In prebored hole processing mode, prebored hole corresponding on bent axle and flywheel must be carried out with boring before connecting with flywheel by bent axle
Hinge, i.e. completes, to prebored hole corresponding on two components, the processing that drills and reams in same operation simultaneously, general with the processing that drills and reams at present
Rely on radial drilling machine or directly use light-duty Boring machine.

Can independently operate, plant maintenance is also required to by professional in addition, so using radial drilling machine to carry out with the processing that drills and reams work
Industry personnel fit hilllock property and there is certain limitation；
4, a whole set of radial drill equipment is gone into operation and platform position laying expense is of a relatively high, needs complete equipment during use
Lubricating system, cooling system, main shaft feed change and Circuits System etc. do periodic maintenance, thus the early investment of equipment and later stage throw
Enter the highest；
5, the site area that radial drilling machine need to take is relatively big, and cannot realize flexible, move operation easily, can only be by work
Part is processed before being transported to lathe.
Use light-duty Boring machine directly to carry out needing to adjust seat in the plane according to the distribution of prebored hole with the processing that drills and reams to operate one by one,
Position, hole when therefore operating adjusts operation, cutter operation all needs to take crane gear, a general machine need half a day to the time,
Thus cause a large amount of wastes of hold facility time.
From the point of view of state-of-the art situation, the operator scheme of similar radial drill can be reached, equipment can be taken into account again simultaneously
